Howdy,
I'm not a user of Asymptote but am trying to help out someone who does use Aymptote. Would someone who uses Asymptote with TeXShop 2.33 please try out the enclosed latexmk engine? Hopefully it does all the correct compiles and bibtex/makeindex runs, etc.
There are two files:
Place the asymkrc file found in `for Asymptote/bin/tslatexmk/' into ~/Library/TeXShop/bin/tslatexmk/ and the asymk.engine file found in `for Asymptote/Engines/' into ~/Library/TeXShop/Engines/.
Restart TeXShop and you can then compile using the asy engine by placing the line
% !TEX TS-program = asy
at the top of the file.
Please let me know whether it's doing the job correctly.
Good Luck,
Herb Schulz
